|\ | | | | | | | | | | | | | | | | | | | | | | bug #877, bug #572: Get rid of Index conversion warnings, summary of changes: - Introduce a global typedef Eigen::Index making Eigen::DenseIndex and AnyExpr<>::Index deprecated (default is std::ptrdiff_t). - Eigen::Index is used throughout the API to represent indices, offsets, and sizes. - Classes storing an array of indices uses the type StorageIndex to store them. This is a template parameter of the class. Default is int. - Methods that *explicitly* set or return an element of such an array take or return a StorageIndex type. In all other cases, the Index type is used.

| * Fix many long to int conversion warnings:Gravatar Gael Guennebaud2015-02-16
| | | | | | | | | | | | - fix usage of Index (API) versus StorageIndex (when multiple indexes are stored) - use StorageIndex(val) when the input has already been check - use internal::convert_index<StorageIndex>(val) when val is potentially unsafe (directly comes from user input)

* | | bug #936, patch 1.5/3: rename _FUSED_ macros to _SINGLE_INSTRUCTION_,Gravatar Benoit Jacob2015-01-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | because this is what they are about. "Fused" means "no intermediate rounding between the mul and the add, only one rounding at the end". Instead, what we are concerned about here is whether a temporary register is needed, i.e. whether the MUL and ADD are separate instructions. Concretely, on ARM NEON, a single-instruction mul-add is always available: VMLA. But a true fused mul-add is only available on VFPv4: VFMA.

| | | | | | | | | | | | | | | | | | | | | | | | | | | in both GCC and Clang on ARM/NEON, whereby they spill registers, severely harming performance. The reason why the asm comments make a difference is that they prevent the compiler from reordering code across these boundaries, which has the effect of extending the lifetime of local variables and increasing register pressure on this register-tight code.
